either toward the left or the right of the stack of cards;

Fig. 12 is a sectional view. taken on the plane of the line i2l2 of Fig.11, looking in the direction of the arrows.

Referring to Fig. l, 29 indicates in its entirety the card filingequipment embodying the invention. which is preferably supported andcompletely enclosed in a housing, such as an ofllce desk. having a desktop 2!, and the usual side and end panels 22, 22, these panels beingcarried by the corner posts 24 and the intermediate posts 25 and 29.

The inside panels 23 carried by the intermediate posts 25 and 26 definean open space below the table top 2 I which may be used for receivingthe feet and legs of the operator sitting in a chair in front of theopen space 21, but in some embodiments of the invention this space maybe utilized for additional equipment.

This form of the invention provides drawer space for drawers at eachside of the operator. which drawers are located between the posts 24-26.

In some embodiments of the invention the table top may be cut oflimmediately toward the right of the right-hand posts 25. providing aform of desk similar to those which are utilized for clerical employeesor stenographers, and in other forms of the invention the desk top maybe limited to a size suitable for covering one drawer space above adrawer which is located between the posts 24, 26.

The equipment preferably includes a pair of drawers, indicated in theirentirety by the numerals 28, 29 in Fig. 1; and, as each of these drawersmay be identical in construction, only one of them will be described.For example, the right-hand drawer 29 may be provided with a pair ofsides 30, the front and rear walls 2|, 22. and a bottom wall 32, and itsfront wall may be separated into two pieces. the lower piece beingindicated by the numeral 24. and the upper one by the numeral 25.

The upper part of the front wall is hinged by means of hinges 26 so thatit may be turned down to lie flat against the front wall 8| and toexpose the eards 31 which are carried by rotatable member 29 for moreconvenient operation. Drawers 22, 29 each are preferably provided withfour rollers 29 located to project from apertures in the bottom wall 32and carried by the side walls 39 adjacent the front and rear walls ll,22.

These rollers 39 rest upon the floor and permit the drawer to be pulledoutward and pushed backward with a minimum amount of effort, and thefront wall 3| may be grasped at its upper edge for this purpose.

Referring to Fig. 4. the rollers 29 are mounted on pins 49. which rotatein the bearings 4i carried by blocks 42. The drawers are also preferablyprovided with suitable horizontally extendins guides 42, 44 mounted onwalls 22, 22 in the form of angle irons or strips of wood for slidablyengaging the guide members 49 carried by the drawer side walls 29. Theseguides may be arranged to retain the drawer in its housing and to limitits outward movement when the guide members 45 strike the front posts24. 25 so that the desk may be handled or turned over without thedrawers falling out.

In other embodiments of the invention the guides 42-49 may be eliminatedafter the desk has been located in its proper position so that thedrawers 2!. 29 may be pulled out and rolled anywhere on the floor of theoffice by means of the rollers 29 for convenient use in any department.

The drawers may be locked by means of a suitable rotatable tumblerbarrel 49 carried by the pivoted part 29 of the front wall II. which hasa keeper that projects, into the slot in the lower side of the desk top2|.

Referring to Figs. 3 and 4, these are sectional views showing apreferred form of the rotatable member which is carried by each of thedrawers 29, 29. This rotatable member is indicated in its entirety bythe numeral 41. and it is preferably mounted on a. cylindrical woodenshaft 42 that is rotatably carried by the bearings 49, ill carried bythe walls 29 of the drawer.

The bearing 49 may consist of a wooden block glued or otherwise securedto the wall 29 and provided with a cylindrical bore ii for receiving thecomplementary end of the shaft 48.

The bearing I0 is preferably of a type adapted to place a predeterminedamount oi friction on the shaft 48. The shaft is preferably providedwith a cylindrical enlargement 92 at this end. The bearing ill mayconsist of two parts. as shown in Fig. 3, each of which is provided witha semicylindrieal bearing portion 52, 54, and with the attaching flangesii, 59, 51, and 98 at the ends of these bearing portions.

The attaching flanges 5i and 59 may be fixedly secured together by asuitable screw bolt or other fastening means. indicated at 99. The twohearing portions 53, 94 are preferably lined with strips of leather,fiber, or other friction material ill, 9| for engaging the enlargedcylindrical portion 52 and placing predetermined friction on the shaftto oppose its rotation.

The amount of friction may be regulated by having the flanges I1. 59spaced from each other, and the lower flange i! may have a nut 82 weldedto it for receiving the lower threaded end 92 of an adjustment screw 64,the annular shoulder 6! of which bears on the upper flange 51.

A knurled handle it permits the more convenient adjustment of thisthreaded member 84 to tighten the parts of the friction bearing ill onthe shaft.

The lower bearing portion 94 may have an attaching flange 61, which issecured to the side wall 29 by screws or other convenient fasteningmeans. and the other bearing portion 53 may have an integral arm 89secured thereto and extending parallel to the side wall 30 of the drawerto which it is secured at its lower end by means of screw bolt 99.

This gives the bearing 50 a point of securement to the side wall at aplace which is at a considerable distance so as to resist the turningtorque which is exerted on the hearing by the shaft 48. Thus thefriction may be so adjusted that, ii desired, the rotatable members willturn freely, or they may be arranged to stay in any adjusted position inspite oi. the fact that certain or the card trays have been removed andthe rotatable member is temporarily out of balance.

The rotatable member 41 may be constructed almost entirely out of Woodby providing the hexagonal end walls 18, 1| oi. wood, having centrallylocated bores 12 for receiving the shaft 48. An auxiliary wooden plate13 on each end wall 18, 1i surrounds the shaft and gives additionalsurface for securement of the rotatable member to the shaft by gluing orother convenient means.

It should be understood that while the present rotatable member is madehexagonal in form for a particular size of cards and a particular sizeof desk or housing, these rotatable members may have more or less sidesand may in fact be made with any desired number of sides.

The end walls 18, H are slotted at their corners, the rectangular slots14 serving to receive the partition frame members 15 01' wood, whichproject radially outward and are provided with elongated rectangularapertures 16 so as to form the elongated pull bars 11.

These pull bars 11 are provided with rounded formations so as to fit thehand conveniently, and they may be used by the operator by pushing orpulling to rotate the rotatable member to bring it to any desiredposition.

In order to provide a plurality of bases and supports for the cards 31,the end walls 18, H

of each rotatable member carry the side walls 18, which are rectangularin plan, and which have their edges 19 beveled and spaced sufficientlyto receive the partition members 15, to which they are glued.

On each side each partition member 15 may carry a sheet metal guide 88consisting of a strip of sheet metal having an attaching flange 8| and aguiding flange 82, these flanges being at an obtuse angle so that theguiding flange extends parallel to the base or side wall 18 of therotatable member.

The guide members 88 may be secured to the partitions 15 by wood screws.Each of the side walls 18 is adapted to carry a card tray, indicated bythe numeral 83, and one form of the card tray is shown in perspective inFig. 5. It may consist of a flat piece of wood, such as the base member84, which may be of plywood, and a pair of relatively narrow end wallmembers 85, 86, which are adapted to carry the cardsupporting bars 81.The base 84 is provided with a slot 88 in each of its edges forreceiving the guide flange 82 of guide members 88 and slots 86 extendalso through the end walls 85, 86.

Referring to Fig. 6, one convenient form of card-supporting bar is shownhere at 81, and this bar preferably has a cylindrical upper portion 88a,a relatively thin body flange 88, and a smaller cylindrical head 88 atits lower edge. The end walls 85, 86 are provided with apertures 8| forpassing these bars, which project into the end walls, but in the endwall 85 the aperture 82 is merely a socket closed at its left end so asto confine the bars 81.

The end wall 86 of the tray has a through aperture 9i so that the bar 81may be removed or placed in their appropriate slots. The base 84 has apair of slots 83, which are wider at the 6 bottgn so that they mayreceive the head of the bar The bars 81 may be held in place on the tray88 by means of a pair or apertured metal plates 86, 88 mounted on woodscrews 84. The end wall serves as a base for slidably supporting thelatching plates 86, 88. which have laterally turned finger-engagingflanges 88 opposing each other.

The plates 88, 88 are slidably mounted on the wall 86 by means of thescrews 81 mounted in the slots I88 in the plates 88, 88, and the platesare pressed apart by a compression coil spring MI. The screws 81 arecarried by the wooden end wall 86, and they are adapted to pass throughthe enlargement I82 in the slot I88 01 each plate, and to secure theplates to the end wall when they are in the position of Fig. 6.

When the flanges 88 are pressed together, the enlarged hole I82 isbrought into registry with the screw 91 so that the plates -86 may beremoved. The plates 96, 86, being secured in a shallow groove in the endwall 88 and extendin over the apertures 9|, the plates hold the bars 81on the trays by engaging the ends of the bars. The bars 81 may beremoved by first removing the plates 85, 86.

The present card filing equipment is adapted to support cards of thetype shown in Fig. 11, in which the cards 31 are arranged in severaldifierent positions.

In the modification shown in Fig. 5, only two bars 81 are employed, withslots I84 of complementary shape in the cards 31.

In the modification of Fig. 11, five of the bars 81 are employed, andthe card which is indicated at 31 is one which is in alignment with theregular stack of cards.

These cards have three slots I84, and they are ordinarily supported bythe three centrally located bars 81. The outer bars 81 serve to supportthe cards when they are in the positions indicated by cards I85 or cardI86. Thus, cards I85 and I86 may be offset from the regular stack 31 fora special purpose so as to indicate which cards need special attention,either for entry on the cards or for the taking off of records from thecards for a particular purpose.

The trays are preferably provided on their lower sides with a partiallyspherical socket I68 (Fig. 3) for engagement with a spring pressed ballIGI that protrudes from the end, but which is confined in a metal tubeI82, spring pressed by a helical spring I63 for engagement with theclosed end I84 of the tube I62.

The ball I iii and socket I88 serve as stops for holding the trays incentered position where the cards will not engage the sides of thedrawers. The ball only projects far enough, however, so that it iscammed into its tube by the walls of its socket when the tray is slid inits sockets to a different position. Thus it serves as an automaticlatching device,

Fig. 12 shows another form of tray in which the construction of the traymay be exactly similar to that previously described, except that thebars 81 are held in place by a wooden strip I81. This wooden strip hasbeveled edges I88, I88, which give its body a dove-tailed form forfitting in a complementary dove-tailed slot H8. The dove-tailed slot isarranged in the'end wall 86 of this tray for receiving the dove-tailedstrip I 81, which holds the bars 81 in their place.

The bars 81 may be removed by first sliding the dove-tailed strip I81out endwise from its slot I I8. The bars 81 may be made of metal or ofany 7 suitable plastic material. In case they are made of plastic. theymay be extruded to the shape shown.

Referring to Fig. 7, this is a. modified form of rotatable member of adifferent construction. In this case end walls III are hexagonal inshape. and they support the side walls III, which are ornamentailyshaped or molded to correspond to and form a continuation of theornamental outer surface of the end walls Ill.

The side walls II! support at each of their ends radially projectingwooden walls II! and Ill adapted to serve as supports for the cards II!and to carry the card-supporting rod Illi.

These radial walls II! and II are preferably formed with outwardlysloping inner surfaces I I1 so that the cards are supported in aslanting position, and their outer surface II! may be omamentally shapedand curved to correspond to the ornamentation n the end walls III andends of the side walls H2.

The rod I I6 is supported in a socket I I9 formed in the radiallyextending wall III, and at its opposite end the radially extending wallI I4 is provided with a socketed plunger I20, having a socket III forreceiving the end of the rod H6.

The plunger I is slidably mounted in a bore I22 and is engaged by ahelical spring I23, the other end of which engages a plate I24. A knobI25 is provided to permit the user to pull out the plunger I20 andrelease the rod IIG.

In this case all of the cards may be removed from the receptacle whichis provided by the side wall II! and the radially extending walls I I3and Ill. The radially extending walls II3, lid are preferably wedgeshaped so that when their edge surfaces I26, II! are joined to the edgesurfaces of similar wall members, a complete rim with a circularperiphery I28 is provided for bordering the index cards that are carriedby this rotary member.

Referring to Fig. 8, this is a rotary member of similar construction tothat of Fig. 7 except that a separate metal or ilber or plastic tray I29is provided for supporting the rod I30 and the cards iii.

In this case the tray I" has a flat body portion I32 and diagonallyupwardly extending flanges I33, ill at each end, the slope of whichcorresponds to the slope of surface I35 on the inside of the radiallyextending rimsl".

The tray I29 has punched out of it the ears I31, which extend outwardlyin the plane of the body portion I". These ears are adapted to engageunder the guide flanges I30 of the metal strip I39, which is secured tothe side wall I of this rotatable member.

The opposite wall I is provided with a pair of apertures for receivingthe spring pressed sheet metal bar I", which engages above the ears I31on this side, in the same manner as the flange I38. The sheet metal barI" has a handle I" formed at its outer end and an aperture I 61 forpassing a thin spring I00. which urges it into the latching positionshown in Fig. 8. Thus this latching member I" may be withdrawn to removethe tray III.

In Fig. 7 the radially projecting end walls ill, I are preferablyprovided with the spool type handles Ill located on one of these wallsin convenient position for grasp by the operator in rotating theassembU.

In Fig. 8, however, a diflerent type of handle I" is provided. Thishandle is glued in a socket at the Junction of each of the side wallsIII.

Referring to Fig. 10, this is a tic illustration of another modificationin which the rotatable member I is provided with handles comprisingU-shaped metal rods I carried by the metal side flanges I" of therotatable member I".

Inthiscasetheshaft lliiscarriedbyalinkage consisting of a pair of linksm, m on each side of the rotatable member I. V

The link I may comprise a cylindrical rod Ill, provided at each end withthe bearing fixtures I50, III. The bearing fixture III has a bearingbore I52 for receiving a stub shaft I53, which is mounted on a baseplate I54 carried by the ad- Jacent panel of the desk, such as, forexample, a panel carried by the posts 25. At its upper end the bearingportion I on the link I carries the shaft I, which supports therotatable member I43.

The link I 41 may comprise a cast metal member having a bearing portionI55 at its upper end mounted on a stub shaft I56 carried by the insidepanel of the desk. At its lower end the lever I4! is pivotally mountedby means of the bearing portion I51 and the trunnion I58 on the sliderI59, which carries the trunnion I58.

The slider I59 is slidably mounted on the cylindrical rod I49. Thelinkage shown in Fig. 10 has two positions, the operative position,which is shown in full lines, and the storage position, which is shownin dotted lines.

The operation of this embodiment is as follows: The operator may graspone of the U-shaped handles I, and may rotate the rotatable card indexsupporting member I43 until this handle i toward the top. Then theoperator may hit the assembly by means of the handle I and pull thehandle I inward toward the position of storage. When this is done, theslider I" will slide down the arm I49 and the shaft I48 will pivot overalong the are shown until it reaches the dotted line position.

It, is only necessary to exert a lifting force until the shaft I46 haspassed its highest position, after which it will automatically drop intothe dotted line position shown in Fig. 10. The weight of the mechanismand the rotatable member and cards will hold the linkage in either ofthe positions shown, after it has once moved to that position.

The operation of the mechanism shown in Figs. 1 and 2 is as follows: Thepull bars Il may be used by the operator for effecting a rotation of therotatable member 38 on its shaft. Assuming the mechanism to be locked upin storage condition, the drawer may be opened by applying a key to thetumbler lock 40. When this look is opened, it will permit the hingeddoor I5 to swing down against the end portion 34 of drawer II. Then theoperator may grasp the upper edge of the drawer and II to pull thedrawer out,

If the drawer is pulled out three fourths way, the cards may reach theposition shown in Fig. 3, where the cards, which are at the upper left,are in a position to be used with data that extends crosswise of thelength of the card. The operator would then move his chair to such aposition that he could look at the cards in the manner of the leaves ofa book.

When it is desired to use the cards for recording data with the printextending endwise oi the card, then the drawer may be fully withdrawnand the cards that are being used may be moved to the upper horizontalposition by means of a Dull bar II.

The brake on the shaft may be so adjusted that the rotatable member willbe held in any position to which it is moved, and the brake friction maybe increased whenever certain trays are removed to effect this holding,in spite of the assembly being out of balance.

Whenever any card is to be removed, it may be pulled off the bars 81 inthe usual manner, preferably by effecting a, slight twist, and it may beplaced back on the bars by merely pushing it into place. During thisaction the adjacent portions of the card bend on account of theirresiliency, but they are not broken or creased: and when the cards arereplaced, the bars 81 are adapted to support the cards in any positionwhich they may assume on the rotatable member.

When it is desired to utilize the card filing equipment at a pointremoved from its housing, the drawer may be pulled out entirely androlled about on the rollers 39. When it is desired to remove one of thetrays, this may be effected with the equipment of Figs. 1 to 3 bysliding the trays endwise out of their guides, with all of the cardscarried on the trail.

The operation of the modifications of Figs. '7 and 8 will be apparentfrom the description of their structure. In Fig. '7 it is possible toremove all of the cards with the supporting rod Hi. In Fig. 8, also, allof the cards may be removed with the rod I30, and the tray I29, as aunit.

In the modification of Fig. 11 provision is made by means of tripleslotted cards and the use of five bars 81 for supporting any of thecards in offset position toward the right or the left of the stack ofcards. This is advantageous whenever it is desirable to segregate cardswithout removing them from their regular order.

It will thus be observed that I have invented improved card fillingequipment, by means of which a great number of cards may be supportedand this equipment may be made practically entirely of wood, so that itis not necessary to utilize much metal at a time when metal is scarce.The present card filing equipment permits the operator to examine orremove the cards with a minimum amount of effort and to find the cards,which are suitably indexed and segregated in the easiest manner.

The pull handles may be provided with indicia for identifying thesections of cards and indicating separators which may be used on thecards wherever desired.

The present device is provided with a, simple, yet effective brake forholding the rotatable member in any position to which the operator maymove it, without placing too much friction on the rotatable member,which would otherwise tire the operator.

The present arrangement is flexible, as it may be made in unitsembodying two or more rotatable members, or it may be embodied in asmaller desk or a single housing containing a single rotatable member.

While I have illustrated a preferred embodiment of my invention, manymodifications may be made without departing from the spirit of theinvention, and I do not wish to be limited to the precise details ofconstruction set forth, but desire to avail myself of all changes withinthe scope of the appended claims.
